What is Room-Temperature InSb Photodiode about?

Researchers in Japan developed an uncooled mid-infrared photodiode based on indium antimonide that operates at room temperature. The device detects thermal radiation from the human body in the 3-25um range, allowing it to potentially save power by turning systems off when no people are present. The researchers optimized the material doping and structure to reduce diffusion current and improve infrared absorption. The resulting photodiode demonstrated a responsivity of 1900V/W and detectivity of 2.8x108Hz1/2
